The contact between polymyxin B and human blood cells produced a double effect on the haemolytic activity of Listeria monocytogenes, L. seeligeri and L. ivanovii hemolysins. At low polymyxin B concentrations the antibiotic promoted erythrocyte lysis whereas at higher antibiotic levels, hemolysis inhibition was observed. According to the effects of polymyxin B, hemolytic profiles were established for each hemolysin. L. monocytogenes and L. seeligeri exhibited a similar profile with maximum… CONTINUE READING
